Answer:
[tex]a=4m/s^2[/tex]
Explanation:
Using Newton's second law:
[tex]F=ma[/tex]
Where [tex]F[/tex] is the force applied on the object, [tex]m[/tex] is the mass of the object, and [tex]a[/tex] is the acceleration.
In this case we need the acceleration, so we clear for [tex]a[/tex]:
[tex]a=\frac{F}{m}[/tex]
we know that the force is: [tex]F=20N[/tex], and the mass: [tex]m=5kg[/tex]
so the acceleration:
[tex]a=\frac{20N}{5kg}[/tex]
[tex]a=4m/s^2[/tex]
the acceleration of the block is: [tex]a=4m/s^2[/tex]
